Reasons to not use Gmail

They quietly discard email deemed to be too offensive for your delicate
sensibilities or something, and they don't even tell you (the recipient,
not the sender).
My mail-server is told that it was accepted, and my smart-phone (which
syncs with Google) is told that it arrived, so where the bloody hell
is it (and no, it's not in the spam folder)?
This is EVIL.
How hard would it be to quarantine it instead, and let me decide for myself?
It seems to have nothing to do with DKIM (or lack of it).

Many of their servers are listed on various DNSBLs, and they don't care;
I'm getting tired of whitelisting random users who use
“Reply All” instead of “Reply to List”
(another whinge of mine). I'll probably end up removing
all those exceptions and let nature have her way…

They are a notable source of spam.

They rotate amongst various servers when being rejected, instead of
taking the standard SMTP response code
“550 5.7.1” as
FOAD.

They appear to be rejecting (out of band) my (in band) rejections, in
direct violation of best practices (if not an outright RFC violation).

Related to the above, they appear to be accepting then rejecting email,
thereby spamming some poor sod whose address was forged.

They have no “postmaster@” and
“abuse@” addresses in violation of the RFCs,
nor indeed any discernible spam-reporting addresses at all.

They gratuitously subscribe you to Gmail+, which appears to be some
wanky social forum or other.

Similarly, they send you unwanted YouTube crap (which I would never
use in a fit); given that Google own YouTube, I guess they won't take
any action…

The "Spam" button is idiotically next to the "Delete" button, and in
the same style.

They ignore all feedback.

They appear to share your personal information, if you were idiotic
enough to click upon their “Yes, I agree to sacrifice my first-born
upon your altar” i.e. “We Are Too Big To Be Blocked”.

Further to the above, I created a new domain and sent mail to it from
my Gmail account (the only place that I've ever used it, ever, and it's not
the WHOIS contact); that email address started getting spammed shortly
afterwards. Coincidence?

It seems that they're into RST-scanning the net; this from a TCPDUMP that
I happened to be running at the time:

If they want to know whether I'm running a web server, then why not be
honest and just connect to it?

“Don't be evil”, huh?
You be the judge.
(Update: they have quietly dropped the "no evil" mantra; hmmm…)

Consider using Hotmail instead; they have
really cleaned up their act, and actually have a reporting
address.

Comments from Gmail-droids will be cheerfully ignored (but possibly
shared and/or posted here), and additions are sought if they can be proven.

And if you think that I have an attitude towards Gmail lusers, you're probably
right; are they too cheap to get a real email address?

If you're silly enough to want to email me (and fancy your chances
of getting past my
spam filters) then try
here;
if you are a filthy spammer who wants to be added to my
oubliette
then you can't go past
this
link.

If you're morbid enough to want to see my excuse for a home page
then it's over
here
somewhere.
